Depends on the territory, the world isn't homogeneous. For the most part we're talking maybe early 17th century. Gunpowder exists but not in any form that'd be superior to magus, so firearms aren't a big thing. Mostly muskets. Harnessed electricity isn't about, but steam technology is just being researched now by the folks in The Darkling Domains. Instantaneous messages and stuff exist, though, if only through magus.
